Open Source

Building for the Public Good

We believe in sharing knowledge and tools with the scientific community. Our open source projects make advanced laboratory equipment accessible to researchers worldwide.

Featured Project

OpenFlexure Optical Tweezers

An open-source extension that integrates laser-based optical trapping capabilities into the OpenFlexure Microscope platform.

Watch: How to Build Optical Tweezers

Interactive Microrheology Simulation

Experience how optical tweezers work in microrheology applications. This interactive simulation demonstrates trap dynamics, Brownian motion, and particle behavior with real physics examples.
